This thread made me smile so big
Siren is a really cool little dog and I'm so happy that she's settled in well with you!
Mexidogs are expert problem solvers, I think it's in their genes. I wish I had taken a video, someone once brought one of those board puzzle toys to the canine refuge that we used to have. It's the kind with the little slots they have to push around in order to reveal the food, and all the dogs immediately figured out how to get the food. My border collie had no clue, she just got frustrated, then pissed off, and picked the whole thing up and threw it on the ground.
